Viral Interferon Regulatory Factor 1 of Kaposi's Sarcoma-Associated Herpesvirus Interacts with a Cell Death Regulator, GRIM19, and Inhibits Interferon/Retinoic Acid-Induced Cell Death

Abstract excerpt

Kaposi's sarcoma-associated herpesvirus (KSHV) plays a significant role in the development of Kaposi's sarcoma, primary effusion lymphoma, and some forms of multicentric Castleman's disease. The KSHV open reading frame K9 encodes the viral interferon (IFN) factor 1 (vIRF1), which downregulates IFN- and IRF-mediated transcriptional activation, and leads to cellular transformation in rodent fibroblasts and...
